Cookie HTTP / HTTPS problem

[quickola]

I have a weird problem. It seems that in some odd cases on some computers... not all just like 1 % or so of the users experience the following problem.

The cookie is set properly with the help of this code:

setCookie( $cookiename , $sessionnumber );

I am just looking for a cookie that will expireat the exit of the browser so I havent included any expire-time.

I have also tried the following code without any luck in adressing the issue:

setCookie( $cookiename , $sessionnumber, 0, '/', $serverurl );

Anyway... the problem is as follows... As long as I stay on http protocol the session works fine, meaning the cookie is set properly and working... but the moment I change over to the https protocol somehow my session is cleared and everything is empty.

As i mentioned this only happens in very rare cases and I havent been able to find any comon causes for this.

Does anyone here have any idea how to address this problem or have had any experiences like this?

Thanks.

Well... Thanks for all the input guys :p Anyway... I have been doing some research on the problem and I think I have come to the conclusion that this might have something to do with a thread issue. That in some cases the server might keep the sessionfile locked in one thread while it try to read it in another in the transition between http -> https.

Since I have the cookie available in both protocols I have tried rewriting my session class to use a database for the most critical data instead of the sessionfiles. That should hopefully solve my problems. My initial tests on this issue has been possitive.
